The level
What reading counts.
The part
What it is
A specific value or event rather than a direction. “Rising” is not a threshold.
Set with reference to the lead time: the threshold has to fire early enough for the organisation to act.

The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
